:FAIL
echo Invalid password

:MDLocker
md Locker
echo Locker created successfully :)
goto End
:End

change the highlighted text with your desired password.

• Now, save it as xxx.bat file (xxx is the name of file). [see screenshot of this step]
  
• Copy or move this file to any place where you want to create an folder having protection.
• Open it. It will create an folder named Locker in that place.
• Now, again open this xxx.bat file and type Y to lock this folder.
• This will hide and lock your folder.

Procedure for Opening or un-locking folder:

•  After locking/hiding a folder you should know about unlocking/un-hiding it.
• Again open that xxx.bat file and type your password
• This will un-hide that folder named locker and you can access the data.

Procedure for Disabling Protecting:

When you have un-locked the folder using above steps, Open that xxx.bat file and Type N instead of Y and folder will behave as a common folder.

Saving  xxx.bat file to a secure place:

You can save this xxx.bat file to any place. Then, to un-lock the folder you have to put that xxx.bat file to that location where you created the folder. In this way, you can manage and lock several folders by using only on xxx.bat file
